Method
Prep
- Preheat the oven to 375F and line a 12-cup muffin tin with liners if desired.
- Beat the cream cheese filling ingredients together until smooth, then refrigerate while you prep the rest of the components.
- Make the oat crumble by combining the oats, flour, brown sugar, and cinnamon, then cutting in the cold butter until crumbly; refrigerate.
Make muffin batter
- Whisk the all-purpose flour, baking powder, baking soda, cinnamon, and salt until evenly combined.
- Whisk the melted butter, packed brown sugar, eggs, sour cream, milk, and vanilla until smooth and glossy.
- Fold the flour mixture into the wet ingredients just until no dry streaks remain, then fold in the finely diced apples.
Assemble and bake
- Fill each muffin cup halfway with batter, then add about a teaspoon of cream cheese filling in the center.
- Cover the filling with more batter so the cream cheese sits inside the muffin center.
- Top each muffin with the refrigerated oat crumble so it forms a crunchy crown.
- Bake at 375F for 22-25 minutes, until the tops are golden and a toothpick comes out mostly clean with no wet batter.
Notes
Refrigerating the cream cheese filling and oat crumble helps them stay distinct inside the muffins, so the center stays creamy and the topping stays crunchy. Store baked muffins in an airtight container in the refrigerator for up to 4 days; rewarm in the microwave for 10–15 seconds. Freeze up to 2 months; thaw overnight in the refrigerator and rewarm. For a lighter option, use low-fat sour cream and reduced-fat cream cheese (texture will be slightly softer).
